The USC Roybal Institute maintains a regularly updated database of academic literature and relevant research reports that are published by its faculty. The online library is not intended to be exhaustive, but we hope it provides useful information for researchers, policy advocates, health service providers and others who wish to learn more about aging and diverse populations.

Please Note: Many online journals require registration and payment to access full-length versions of articles. Faculty, students and staff at universities and colleges can often access electronic journals through their online campus library network for free or at a minimal cost. Some public libraries also provide such access to its members. Please contact your public or university library for more information.

Participant perspectives on online interventions for diverse caregivers of persons living with dementia

Caregivers reported positive appraisals of the program’s acceptability. Time constraints and a desire for more peer interaction were prominent. Key themes included programmatic features, cultural and gender considerations, program and research participation, and suggestions for improvement.

Current and Future Replacement and Opportunity Costs of Family Caregiving for Older Americans With and Without Dementia

Current annual replacement cost of unpaid family care is between $96 and $182 billion, 44 percent of which is accounted for by dementia caregiving. By 2060, it will increase to $277-571 billion, and 53 percent will be for dementia caregiving. The opportunity costs of forgone earnings and productivity loss, however, will grow faster, increasing from current levels of $107 billion and $26 billion to $380 billion and $102 billion, respectively, in 2060. Projections show that opportunity costs of family caregiving will be increasingly borne by caregivers of older adults with dementia and racial/ethnic minoritized caregivers.

Economic Burden of Alzheimer Disease and Related Dementias by Race and Ethnicity, 2020 to 2060

The findings of this study suggest that African American and Latino older adults with ADRD and their families are likely to face disproportionately high burdens, primarily associated with unpaid caregiving. Understanding ADRD prevalence, comorbidity, inadequate care, and support policies may attenuate economic burdens for all US residents.
